1. A significant number of Swedes were in Lombardy (northern Italy) at the time the European outbreak started there. Furthermore Sweden has at least two major companies with presence around Wuhan. So by the time government noticed the issue it was too late.
2. Elderly care employees in Sweden are basically gig workers, resulting in a huge rotation in care givers and further spreading of the virus. The Social Democrats (and the Left party V) have often been opposed to this.
Two more things to consider:
1. This difference between Sweden and its neighbours is also clearly visible in the flu pattern over the year. It is simply due to different living and travelling conditions.
2. The municipalities are somewhat independent of the central government. Some with the highest death numbers among the elders where controlled by the opposition (e.g. Stockholm).
So while the government could have done a MUCH better job, your comment is already fairly partisan by cherry picking or ignoring facts.
